Cause

Tilladelserne til /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml er forkerte:

ls -thrl /usr/local/avamar/var/mc/server_data/prefs/
total 68K
-r-------- 1 admin admin 4.5K Jun 23 20:50 preferences.dtd
-rw------- 1 admin admin 7.2K Jun 23 20:50 avamar_keystore
-rw-r--r--  1 admin admin 44K Jun 23 20:51 mcserver.xml
-rw------- 1 admin admin 20 Jun 23 20:57 mcecroot.flg
-rw------- 1 admin admin 20 Jun 23 20:57 mcrsaroot.flg
 

Filen og gruppen skal være admin, og tilladelserne skal være 664:

-rw-rw-r--  1 admin admin 44K Jun 23 20:51 mcserver.xml

Resolution

1. Ret tilladelser og ejerskab efter behov:

chown admin:admin /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
  
chmod 664 /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml
 

2. Kontrolere:

ls -thrl /usr/local/avamar/var/mc/server_data/prefs/
total 68K
-r-------- 1 admin admin 4.5K Jun 23 20:50 preferences.dtd
-rw------- 1 admin admin 7.2K Jun 23 20:50 avamar_keystore
-rw-rw-r--  1 admin admin 44K Jun 23 20:51 mcserver.xml
-rw------- 1 admin admin 20 Jun 23 20:57 mcecroot.flg
-rw------- 1 admin admin 20 Jun 23 20:57 mcrsaroot.flg
